SPECIFICATION forming part of Letters Patent No. 307,915, dated November 11, 1884.

Application filed April 3, 1884.

(No model.)

To aZZ whom. it may concern:

Be it known that I, Bonner S. CLARK, a citizen of the United States, residing at Helena, in the Territory of Montana, have invented certain new and useful Improvements in IVhifiletree-Olips, and I do hereby declare the following to be full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of whiffletree-clips which are used on double or single trees for connecting the single-tree to the double-tree or to the trace for which on the 20th day of November, 1883, Letters Patent of the United States were granted to me; and the nature ofmy invention consists of a novel combination of parts whereby the clip is rendered detachable and adj ustablc, and capable of being removed or replaced with facility.

J In the accompanying drawings, in which corresponding parts are designated by similar letters, Figure l is a side view, and Fig. 2 a plan View, of the device. Fig. 3 is a plan View of the under side of the device, and Figs 4 and 5 represent the parts thereof detached from each other.

The device consists of two pieces of plate, sheet, or cast metal, A and B, each of which is so formed, cast, or put that when they are hinged or pivoted together they may be made to encircle the ends of the single-tree or part to which they are attached. The end of the upper part, A, projects forward from the part which clasps the whiffletree in such a manner as to form an extended plate, Z), and hook O, and the end of the lower part, B, is extended forward in a similar manner to form the plate I) and hook G. The pieces A and B are connected together by forming their edges in such a manner that they interlock with each other. In other words, projections formed on the one project within slots cutin the other. An opening, D, is cut in the upper part to form the hook, and a projection, d, of similar size and shape is formed or cast upon the lower part, which exactly fits within it. A similar opening, D, is cut on the lower part to form the lower hook, and a projection, d, of similar size and shape is formed or cast on the upper part to fit within it. By this construction the parts 'ing lugs h, which travel. upon the said spiral surfaces or shoulders h, and upon the under sides of the spiral surfaces are cut nicks or notches 0, so made and arranged that when the bolt is turned or forced home the lugs h catch within the nicks or notches 0, and thus the bolt is secured in position. In some in stances it may be desirable to prevent the clip from slipping on the single-tree or part to which it is attached, and to effect this purpose I provide projections 011 the interior surface of the clip, which may be made to enter holes prepared for their reception in the single-tree, as shown and described in the Letters Patent granted to me and hereinbefore referred to.

In order that the parts may be cast and manufactured with facility, I provide the clip with a hinge ofnovel construction. This hinge is made bycasting upon the upper section of the clip a cylindrical projection, M, and cutting-or casting adjacent to such projection a longitudinal opening, or. Upon the lower part of the clip a hook, N, is cast, which is passed through the longitudinal opening, and rotated about the cylindrical projection until the parts come together.

In operating the clip the ring or link is passed first over one hook and then over the.

other. The pieces A and B having been made to encircle the tree to which the clip is to be attached, the parts are closed, and the projecting lugs of the one part are made to fit within the openings or slots of the other. The lock ing-bolt H is then passed downward through the holes I, the nicks or notches cut in the sides of said holes allowing the lugs upon the bolt to pass freely. The rotary motion of thebolt upon its axis causes the lugs to travel upon the inclined curves or spiral surfaces 8 until they catch in the notches cut on the bottom thereof, and thus are made to hold the bolt firmly in position.

Having thus described my invention, Iclaim the part A, having a book, 0, and projection and desire to secure by Letters Patent of the (Z, and the part B, having a hook, O, and pro- United Statesjection d, as and for the purposes described.

1. The locking pin or bolt H, having lugs In testimony whereof I aflix my signature in formed thereon, the plate A, having a hole cut presence of two witnesses. therein and the olaite B havin a hole on the w i r lower edge of which a spiral Sl1fil06 provided ROBERFL CLARK with a, notch is formed all combined as and for the purposes described.
